Title: Process for retreading a worn tyre
IPC: C08J5/12
Filed: 1975-12-02
Abstract: 1503027 Retreading tyres ITAL-RUBBER SRL 2 Dec 1975 [21 Jan 1975] 49535/75 Heading B7C A tread assembly for use in retreading a tyre comprises a premoulded tread 1, a perforated sheet 3 of vulcanizable bonding material containing an anti-scorching agent which prevents vulcanization below a temperature in the range 35 to 40 C., and a protective film 3a. The tread assembly is assembled in the apparatus of Fig. 2. The sheet 3 and superposed tread 1 are passed through a first pair of rollers 17 and then through a second pair of rollers 4, 5. The roller 5 has pointed projections 6 which perforate the sheet 3. The tread 1 and perforated sheet 3 are subsequently passed into vacuum chamber 7 to cause expulsion of any air located between the tread and the sheet, or in the perforations of the sheet. Before the tread and sheet leave the vacuum chamber, the protective film 3a is applied to the free surface of the sheet to prevent air from returning to the perforations of the sheet. In the retreading process using the tread assembly, the protective film 3a is first removed and then the tread 1 and sheet 3 are applied to the rasped surface 2a, Fig. 3, of the tyre 2. A protective casing 8 is positioned around the tyre, and the tyre is placed in a vulcanizing oven 12. The vulcanizing oven is provided with a pipe 15 for use in inflating the tyre, and with a pipe 13 for use in evacuating the interior of the protective casing. Vulcanization to vulcanize the sheet 3 is carried out at about 100 C. by pressurizing the oven with a heating fluid.

The apparatus comprises fixed shaft 1, Fig. 3, bearing fixed gear 6 and rotatably carrying sliver can supports 2 and 3, both supports having can lifting gear. Support 2 has motor 7 to rotate the support via pinion and engaging gear 6. Pinion 12 rolls on gear 6 and is connected by a crank mechanism to support 3 to rotate the support 3 about shaft 1 and to move it relative to support 2. In use, Fig. 4, an empty can is loaded onto support 3, and a can of coiled sliver fed from source 16 is loaded on to support 2. The supports are then rotated, the empty can initially catching up and abutting the full can, Fig. 5, to facilitate the transfer of continuously fed fibre. While the empty can is moving into position, Fig. 6, the full can is carried to a removal station. The two cans are then deposited, and the supports back-rotated to the Fig. 4 position. The lifting gear may be operated automatically. The crank member 13 is adjustable both in its length and in its position of pivotable attachment to support 3.

Heading C7B. In the reduction of organic compounds using mercury amalgam preferably in an electrolytic cell, the aqueous phase of the reaction is withdrawn and freed from organic products, and the aqueous phase containing alkali metal or alkaline earth metal ions passes to an electrolytic cell together with mercury, where the amalgam is re-formed, and the aqueous phase now depleted in alkali metals &c. is re-charged with organic starting materials, and is re-cycled to the first reduction stage. The process may be in continuous cycle including the flowing mercury cathode. The process is applied to α-#-ethylenlcally unsaturated compounds e.g. esters, amides, nitriles and especially acrylonitrile to form adipo-nitrile. The aqueous, solution normally includes valuable components e.g. tetraalkyl ammonium hydroxide or sulphonate, and N: N di-methyl nitroso-aniline, which are retained unchanged in the regeneration stage. For examples the hydro-dimerisation of acrylo-nitrile is described using these compounds in an aqueous medium containing buffer salts, and maintained at pH 5-11 by addition of phosphoric or hydrochloric acid. The figure is a flow sheet in which TeaCl is tetra-ethyl ammonium chloride. ADN is adipo-nitrile, ACN is acrylo-nitrile, and PN is propio-nitrile.
